CVE-2025-37165

7.5 HIGH

📋 TL;DR

A vulnerability in HPE Instant On Access Points router mode configuration exposes internal network configuration details through packet inspection. Malicious actors can gain unauthorized knowledge of network topology and configuration. This affects organizations using HPE Instant On Access Points in router mode.

💻 Affected Systems

Products:
  • HPE Instant On Access Points
Versions: All versions prior to patched firmware
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects devices configured in router mode; bridge mode devices are not vulnerable.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain complete network topology visibility, enabling targeted attacks on internal systems, credential harvesting, and lateral movement planning.

🟠

Likely Case

Attackers discover internal IP ranges, device types, and network structure, facilitating reconnaissance for future attacks.

🟢

If Mitigated

Limited exposure of non-critical configuration details with minimal impact on overall security posture.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires network access to capture packets from affected devices.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to HPE advisory for specific firmware versions

Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04988en_us&docLocale=en_US

Restart Required: Yes

Instructions:

1. Access HPE Instant On management interface. 2. Check current firmware version. 3. Download latest firmware from HPE support portal. 4. Upload and apply firmware update. 5. Reboot access point.

🔧 Temporary Workarounds

Switch to Bridge Mode

all

Configure access points in bridge mode instead of router mode to eliminate the vulnerability

Network Segmentation

all

Isolate affected access points on separate VLANs to limit exposure

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate affected devices
  • Deploy network monitoring to detect packet capture attempts

🔍 How to Verify

Check if Vulnerable:

Check if HPE Instant On Access Points are configured in router mode via management interface

Check Version:

Check firmware version in HPE Instant On management interface under System > Firmware

Verify Fix Applied:

Verify firmware version matches patched version in HPE advisory and confirm router mode configuration no longer leaks data

📡 Detection & Monitoring

Log Indicators:

  • Unusual packet capture activity on network segments containing access points
  • Multiple connection attempts to access point management interfaces

Network Indicators:

  • Unusual traffic patterns targeting access points
  • Packet capture tools detected on network

SIEM Query:

source="network_sensor" AND (event_type="packet_capture" OR protocol="802.11") AND dest_ip="access_point_ip_range"
